Abstract
Description
- A present invention relates to a portable wireless device and in particular to a portable wireless device and a wireless communication method in that a metal part of expandable mechanism functions as an antenna.
- In recent years, portable wireless devices having various shapes have been developed. Although "fold-type" which can variably set both an expanded status and a contracted status of the device using a hinge mechanism was considered ordinary as a mainstream, an expandable-type portable wireless device using sliding mechanism or rotating mechanism also has been developed.
- In the expandable-type portable wireless device, metal component is often used in the expandable mechanism (i.e. mechanism of freely set both expanded status and contracted status) for ensuring strength.
- In addition, the fold-type portable wireless device using the hinge mechanism includes metal components in the hinge part for ensuring strength. So, it is supposed that "expandable mechanism" also includes a hinge mechanism in the following descriptions.
- Here, in the portable wireless device with the expandable features, a location of an antenna in housings is a significant factor that influences the antenna characteristics.
- As a technology in relation to the antenna of the expandable portable wireless device, a
patent document 1 disclosed "A PORTABLE RADIO APPARATUS". In the invention of thepatent document 1, a first chassis and a second chassis are connected at a junction part where a conductive metal is included in order to support both of opening and closing mechanism, a ground layer of the printed wiring board arranged in the respective chassis is electrically connected to another ground conductor thereof, and the ground conductor is contacted to the conductive metal. - However, in the expandable-type portable wireless device of the
patent document 1, in the case that the antenna is arranged at the part which is an edge of the device in an expanded status, antenna characteristics may degrade due to affection of a human body. - A
patent document 2 discloses a portable wireless apparatus equipped with an antenna element in the neighborhood of expandable mechanism (in other word, nearby a central part at expanded status). In the case that the antenna is arranged at a part which is near the center of the device in the expanded status, the deterioration in antenna characteristic caused by influence of human body of thepatent document 2 can be considered smaller than that of thepatent document 1.
[Patent document 1] Japanese Patent Application Laid-Open No.2006-157283
[Patent document 2] Japanese Patent Application Laid-Open No.2006-180170 - But, when the antenna is arranged near the expandable mechanism like the invention disclosed in the
patent document 2, there is a concern of adverse influence on the antenna characteristics because metallic parts are included in the expandable mechanism. - That is, in the portable wireless device with an expandable mechanism, even it the antenna is arranged in either an edge or near the center of the device in the expanded status, the antenna characteristics might be deteriorated.
- In view of the above-mentioned problems, an object of the present invention is to provide a portable wireless device and a wireless communication method which can transmit and receive wireless signal without affecting influences both of metallic components included in the expandable mechanism and human bodies.
- In order to achieve the above-mentioned object, a first exemplary embodiment of the present invention provides a portable wireless device that can take two statuses of an expanded status in which an upper housing and a lower housing are arranged approximately in series and a contracted status in which the upper housing and the lower housing are overlapped each other. Here, in the portable wireless device, at least a part of expandable mechanism which takes both the expanded status and the contracted status is formed of the metal, and the metal part of expandable mechanism operates as an antenna.
- In addition, in order to achieve the above-mentioned object, a second exemplary embodiment of the present invention provides a wireless communication method of the portable wireless device that can take two statuses of an expanded status in which an upper housing and a lower housing are arranged approximately in series and a contracted status in which the upper housing and the lower housing are overlapped each other. The wireless communication method comprises forming at least a part of expandable mechanism, which makes variable said expanded status and said contracted status, of the metal and operating wireless communications by making a metal part of expandable mechanism operate as an antenna.
- According to the present invention, it can provide a portable wireless device and a wireless communication method that can transmit and receive a wireless signal without affecting influences both of metal components included in an expandable mechanism and human bodies.
-
Fig. 1 shows a general composition of a portable wireless device of a preferred example embodiment of the present invention. Anupper housing 2 and alower housing 7 of the portable wireless device are connected so that they can rotate around center of arotating mechanism 1 that is an expandable mechanism. Here, at least a part of therotating mechanism 1 is made of metal. That is, therotating mechanism 1 has at least a metal component. -
Fig. 2 shows a composition of the portable wireless device. Theupper housing 2 includes an upper substrate 4 and adisplay part 3. In addition, thelower housing 7 includes alower substrate 6. The upper substrate 4 and thelower substrate 6 are connected by a fine line coaxial 5. - However, the
rotating mechanism 1 is electrically disconnected with the upper substrate 4. The electrical connection between therotating mechanism 1 and thelower substrate 6 is performed via any one among joint parts 8-11. That is, the electric power is supplied to the metal part of therotating mechanism 1 by using any one of the joint parts 8-11 as a feeding part, and then, therotating mechanism 1 operates as an antenna. - The metal part of the
rotating mechanism 1 operates like a Planar Inverted F Antenna by supplying electric power from any one of the joint parts 8-11 as the feeding part and by connecting at least one among remaining three of the joint parts 8-10 to GND (the ground), and then, an excellent input impedance characteristics is obtained at a predetermined bandwidth. -
Fig. 3 shows a return-loss during supplying electricity to thejoint 11 and grounding thejoint parts 8 and 9 to GND. InFig. 3 , the return-loss of no more than 5dB is obtained within 830MHz-960MHz frequency bandwidth, so it can be assured that the radio wave within the frequency band can be transmitted in the high quality. -
Fig. 4 shows a return-loss during supplying electricity to thejoint 11 and grounding thejoint parts joint parts 8 and 9. InFig. 4 , the return-loss of no more than 5dB is obtained within 830MHz-960MHz frequency bandwidth, so it can be also assured that the radio wave within the frequency band can be transmitted in the high quality. -
Fig. 5 shows a return-loss during supplying electricity to thejoint 10 instead of thejoint 11 and grounding thejoint parts 8 and 9 to GND as likeFig. 3 . InFig. 5 , the return-loss of no more than 5dB is obtained within 830MHz-960MHz frequency bandwidth, so it can be also assured that the radio wave within the frequency band can be transmitted in the high quality. - Thus, the metal part of the
rotating mechanism 1 can operate as the antenna by setting the feeding part among the joint parts 8-11 and grounding whichever of the remaining joint parts. In general, excellent antenna characteristics can be often obtained by using thejoint parts 8 or 10 being near the edge of thelower substrate 6 as the feeding point. However, in a real situation, the antenna characteristics is changed according to mounting status on thelower substrate 6 of the device and shapes of the metal part (i.e. shape of the metal component) of therotating mechanism 1 or the like, so excellent antenna characteristics may be obtained by using thejoint parts joint parts 8 and 10 being near the edge of thelower substrate 6 as the feeding part. Therefore, it is desirable to select the combination that can obtain the most suitable antenna characteristics according to characteristics of the substrates and the housings. -
Fig. 6 shows radiation efficiency of the portable wireless device. As shown in the diagram, the best antenna characteristics can be obtained when using thejoint part 10 being near the edge of thelower substrate 6 as the feeding part and grounding thejoint parts - Although an electrical combination of selecting the joint part 8 as the feeding part and grounding the
joint parts joint part 10 as the feeding part and grounding thejoint parts lower substrate 6 and thelower housing 7 are asymmetric. Therefore, it is desirable to select the combination that can obtain the most suitable antenna characteristics according to the characteristics of the substrate and the housing. - Here, when the desired input impedance characteristics and the radiation characteristics are not obtained by simply connecting the joint parts 8-11 to the feeding point and GND, these characteristics can be adjusted by arranging coils and the capacitors at the joint parts 8-11 (in other word, by connecting the metal part of rotating mechanism with the feeding point and GND through coils and capacitors).
- Thus, in the portable wireless device according to the exemplary embodiment, because the metal part of
rotating mechanism 1 is connected with the feeding part via one of the joint parts 8-11 and with GND of thelower substrate 6 via at least one of the remaining joint parts 8 to 11 respectively, the metal part ofrotating mechanism 1 and thelower substrate 6 are incorporated to function similar to the Planar Inverted F Antenna. As a result, the metal part of therotating mechanism 1 does not influence on the radiation characteristics of the antenna, and also improves the radiation characteristics. Moreover, because the metal part ofrotating mechanism 1 arranged near the central part at the expanded status operates as the antenna, antenna characteristics does not be degraded by the affection of human bodies during a communication. - In the above-mentioned embodiment, although it has described using the portable wireless device of the rotating type as an example (i.e. with a rotating mechanism as one of an expandable mechanism), even in the portable wireless device of the slide-type and the fold-type, it can also operates as the Planar Inverted F Antenna similar to the above-mentioned device by connecting the metal part of sliding mechanism and the hinge mechanism with GND of the lower substrate and the feeding point respectively by at least one position.
- Further, it is to be understood that to the configurations and details of the invention of the present application, various changes can be made within the scope of the invention of the present application by those skilled in the arts.
- This application claims priority from Japanese Patent Application No.
